The Importance of HLB Hydrophilic-Lipophilic Balance (HLB) of surfactants determines the outcome of the mixture of water-surfactant-oil in a ternary phase diagram.5 Point “P” of the phase diagram (below) represents 65% water, 25% oil and 10% surfactant. Physical characteristics of “P” will vary depending on the HLB of emulsifiers and the nature of the oil phase. Most of the emulsions are located..

Emulsifier for silicone oil SOP-104 1. Brief Product Introduction: Oil emulsification requires precise HLB value. And generally speaking, it is hard for oil emulsification, harder for silicone oil emulsification. But the dedicated emulsifier produced by our company (the adjusted HLB value is suitable for silicone oil emulsification) can be used for the production of methyl silicone oil emulsion,..
